FIX: The MQSC Adapter generates excessive network traffic when it receives messages from IBM WebSphere message queues

View products that this article applies to.

Symptoms

The MQSC Adapter may generate excessive network traffic when it receives message from IBM WebSphere Application Server message queues. The overhead of the network traffic may be 4 to 10 times the size of the actual message that is being received from the message queue. The excessive network traffic can be observed in network traces that are used to capture data between the instance of Microsoft BizTalk Server that is using the MQSC Adapter and the IBM WebSphere system. The BizTalk Server does not report any errors or warnings when this occurs.

Cause

The MQSC Adapter uses multiple MQGET calls when it retrieves messages from an IBM WebSphere message queue. The excessive network traffic occurs because of the multiple MQGET calls that the MQSC Adapter uses when it reads the message.
